  • As can be seen, this week has been devoted to totally different things, first and foremost to getting our first analysed texts ready for corpus inclusion. (and to hyphenation...) I'll just have to move the tasks to next week.

3. Documentation

TODO:

  • finish i18n work (Børre and Sjur)
    • set up Tomcat at the faculty server, and install Forrest as war. Needs testing before being deployed on the server! Thus, install it on the G5 first and see that it works, then on the faculty server.
    • i18n does not work in PDF ("Table of Content" won't translate)
      • still doesn't work
  • Write both user and admin documentation (Børre, review: Sjur, Thomas)
    • User documentation probably in several languages. This covers how to apply for an account, on what grounds one can apply, and pointers to documentation telling how to use the corpus.
    • Admin documentation, telling how we set the permissions to the corpus files, and whatever other processes and tasks needed to set up a corpus account.
      • move these issues into Bugzilla (Sjur)

4. Corpus gathering

Børre talked to Richard Valkeapää, they have several computers, and have the data available. But they have problems with their backup system and interaction between file names on Windows and MacOS X. Børre will help them, and we will receive our data.

TODO:

  • discuss corpus transfer with NSI (Børre)
  • continue to contact authors (Børre)

5. Corpus infrastructure

User accounts and access

The whole issue should be moved into Bugzilla as several tasks.

TODO:

  • add the issue with subissues to Bugzilla (Trond)

More texts to the graphical corpus interface:

Trond, Børre and Saara aligned and sent the first parallell corpus files to Oslo. One milestone further : -)

TODO:

  • align texts, analyse, and send to Lars (Trond, Saara)
  • add text to the server (Lars)

Aligner

Børre has made some important improvements to the Bergen Aligner. The Aligner compiles better and is now able to save intermediate result files (4 out of 5 files, that is, so there is still some work to do), in order to control memory usage. In this way, we are hopefully able to contribute to the Bergen development.

TODO:

  • gather parallel texts (Trond)
    • Trond is working on it
  • try out NT alignment strategies (Saara)

Language recognition

TODO:

  • get more sma texts, first the Bible / NT (Trond)
  • improve the smj LM (Saara)
    • done
  • what about paragraphs with mixed content? Build a corpus of such paragraphs ( Trond)

6. Infrastructure

Xerox tools wrapped as servers

The Divvun project needs generation pretty soon, and Tomi can add generation to the server if he needs it. Possible conflicts in the code will have to be resolved when Saara is back.

TODO:

  • improve and finish the present prototype (Saara)
  • add generator (Tomi)

Hyphenator

Sjur has hyphenated the pl-wordlist.txt file (the full-form word list generated for Polderland), and now has about 10Gb of hyphenated data on his computer! Forgot to use time, but it took somewhere between 36 and 48 hours! There's a lot of noise and problematic issues in the data, but a cleaned version will be sent off to PL for their perusal. The cleaned version is 651Mb, just slightly larger than the original input file, which was 627Mb.

Hyphenation for smj still does not work, as the hyphenation rules file does not compile. We have received valuable feedback from Lauri Karttunen, though, as we reported a UTF-8 bug in the latest versions of the Xerox tools.

Overgeneration problem:

Abakalikilaččabuččaideamet      A^ba^ka^li^ki#lab^bo^žiid^dá^met

Unrecognised input:

abbalaččaboiid          abbalaččaboiid          +?
Abbalaččaboiidda        Abbalaččaboiidda        +?
abbalaččaboiidda        abbalaččaboiidda        +?
Abbalaččaboiiddáde      Abbalaččaboiiddáde      +?
abbalaččaboiiddáde      abbalaččaboiiddáde      +?
Abbalaččaboiiddádeguin  Abbalaččaboiiddádeguin  +?

What is the percentage of unrecognized input? (i.e. of word forms generated by the generator but not accepted by the analyser)? Answer:

  • Wordlist generated = 27 354 884
  • unrecognised wordforms = 11 284 570
  • percentage unrecognised = 41,3 %

This is way too high, and must be investigated. The input is generated from our normative, non-circular version of the lexicon, and should thus only contain recognised word forms already in the lexicon.

TODO:

  • Update the sma hyphenator rule set with the insights gained from smj updates (Trond during weekends)
  • linguistic issues in the hyphenator: ( Sjur using M4)
    • shortening in compounds (grossly overgenerates in the hyphenator output)
      • done - the shortening rules are now filtered out by M4 when compiling the twol for hyphenation and other normative uses
  • consider case conversion problems (Saara)
  • check #- when comparing input string with hyphenated string - the hyphen could be part of the input string, keep it if it is, discard the hyphenated string if not (Saara)
  • investigate unrecognised input word forms (Maaren, Thomas, Trond, Sjur)

Automatic Bugzilla reminder for untouched bugs

Some perl-libraries needed by Bugzilla weren't in the path, causing it to not work. Adding them should fix the issue.

TODO:

  • fix the remaining issues (Børre)

M4

TODO:

  • make speller make targets that utilise M4 to produce normative and hyphenation transducers - postponed a while (Tomi or Sjur)
    • done
  • disamb variants for derivations (see next) (Saara)
    • include make as part of a shell script, which will run the M4 processor on the disamb rules (Saara)
      • done - but the disambiguation REMOVE rules need to be added in again for the benefit of the disamb project. What the syntacticians really want is to have this done in the cg-3 interface.

7. Linguistics

Names and multilinguality

We need a more principled approach to this.

Background: the name lexicon is getting attention from the SD name/terminology sections, and they would like to use our name lexicon also for public searching.

Observations:

1) Multilinguality is always optional.

2) We can observe that "foreign" names in texts follows a domination pattern: majority language forms can be found in minority language texts as real names ("Kautokeino produkter"), whereas minority language names almost always occur in majority language texts as citations. And citations should not be considered a natural part of the text.

3) When looking at our name classification, multilinguality varies according to:

Ani - weak/none? (pet, myth anim.  names)
Fem - weak (informative)
Mal - weak (informative)
Obj - strong
Org - strong
Plc - strong for the national and country names, weak (informative) for foreign
       names
Sur - none
Tit - strong (titles)

Suggestion:

We need to reconsider the all names in all languages policy. That policy is valid only for Fem, Mal, and Sur (and Ani and Tit?). For Obj, Org, Plc the rule should be that if they have multilingual names, each name should only be used in it's own language. Then we need a modification saying that majority language names can be included in minority language lexicons if attested in our corpus. Also, the majority language varies according to country (obviously), which means that in a speller context, we might consider tailoring spellers for each country, leaving out noise relating to majority language names from another country.

A further issue is whether we should reconsider our cohort policy. Today, Sur and Plc are different readings. An alternative would be to have them as secondary tags, not in conflict with each other:

"<Trosterud>"
        "Trosterud" N Prop Sur Sg Nom <<< @HNOUN
        "Trosterud" N Prop Plc Sg Nom <<< @HNOUN
"<Trosterud>"
        "Trosterud" N Prop Sg Nom <Sur> <Plc> <<< @HNOUN
"<Trosterud>"
        "Trosterud" N Prop Sg Nom &Sur &Plc <<< @HNOUN

Derivation and spellers like Aspell

  • enclose the CG rule that preferres lexicalised forms over derivations in M4 ( Saara)
    • done
  • find and study all derived verbs in our corpus (Thomas)
  • suggest which derivations could be generated (Thomas)
  • lexicalise the rest (Thomas)

North Sámi

We have a lot of overgeneration, mainly possible derivations that are spelled out. We need to investigate what is going on, and evaluate whether it is a problem.

TODO:

  • investigate the generated word form list sent to Polderland - use the command make pl-wordlist TARGET=sme in victorio ( Maaren, Thomas)

Lule Sámi

TODO:

  • refine smj proper noun lexica, cf. the propernoun-smj-lex.txt ( Thomas, Trond)
  • hire new linguist (Sjur)

8. Name lexicon infrastructure

Decided in Tromsø:

  • add logging facilities to the interface
  • add option to download local copies of the lexicon files directly from the db
  • batch editing (change all entries in the found set), should later be enhanced to allow selection of exceptions (the found set minus deselected items)
  • tag for excluding/including a name from certain applications
  • future epxansion: choose what info to display in the single language browser
  • display existing language entries when adding a new language to a record
  • add editor to change single, existing entries

Details can be found in the meeting memo.

TODO:

  • develop the needed XQueries and UI (Sjur, Tomi)
  • turn Tomcat on on the G5; send admin username and password to Sjur ( Børre)
  • add eXist and the proper noun interface to the G5 (Sjur)

Postponed:

  • data synchronisation between risten.no and the cvs repo
  • new version of xml2lexc (based on ccat), should handle complex names correct: construct entries like we have now from the different parts of a complex name entry

9. Spellers

News

The Greenlandic speller was released today. It is available at the website of the greenlandic language council. It is available for free, and is based on the same technology as our own.

Speller data generation

It reads the lexc files, reads each word, and requests (or will request) the generator server to expand each base form to its full paradigm.

Still missing: the generator isn't yet available, Tomi should implement a first version while Saara is away. It should allow requests for:

  • single word forms
  • reduced paradigm
  • full paradigm (all possessives, clitics etc, including compound forms)

The Java code needs to be checked in into cvs, suggested location:

gt/src/lexc2xspell

TODO:

  • add code to cvs (Tomi)
  • implement generator server based on Saara's code (Tomi)
  • specify compounding behaviour info for the lexicon (Thomas, Trond, Sjur)
  • add hyphenation points to the generated output (Tomi)

10. Other

Bug fixing

66 open Divvun/Disamb bugs, and 24 risten.no bugs

Guess: 1/3 of the bugs are fixed already (?)

Meetings and the SD Firewall

TODO:

  • investigate use of proxies for Maaren ( Børre)
    • done and solved nicely!
  • document SquidMan use at SD (Børre)

Task lists as iCal entries

TODO:

  • update Maaren's installation to r430284 (Børre)

Words section

You all need to check out CVS/words, and link to the relevant place, cf how gt/doc/ is linked.
